Sand is an ever-present problem for the coastline. The operator therefore has the necessary equipment to regularly clean up sand accumulations. The gripper is specially equipped to fit into the track.
The question is not how fast one can drive, but how fast one is allowed to drive. And that speed is kept low, also by inattentive and ignorant crossing pedestrians, who sometimes (even in adulthood) see tram tracks for the first time in their lives. In this picture you see pedestrians crossing, but they don't always look out and the same day I witnessed an almost serious accident. A whole family stayed on the tracks, while a tram came from far away. The trams on the coast are equipped with a special horn, dating from the Vicinal railway era, which is not allowed to be used in the city: it makes a lot of noise. You hear this from far away and the driver used it too, but people stayed on the tracks. The tram was slowed down and had to stop, while those people stayed on the tracks. The driver effectively got off the tram, made himself angry, but it is clear that 40 km/h is the highest achievable. Driving times have been extended over the years for the same reasons. The straightening of the line in Lombardsijde has confirmed this: the minutes gained there are added elsewhere to reduce speed.
